摘要
针对屯留矿N1203工作面发生由外因引起的火灾,通过采取综合灭火措施,实现了火区封闭。基于火区气体变化规律,分析了封闭火区的燃烧状态,采取对火区增氧的措施进一步确定火区火势的状态。结合《煤矿安全规程》实现了对N1203工作面的安全启封,是高瓦斯矿井启封的一次成功实践。
Aimed at the fire at N1203 working face in Tunliu Coal Mine caused by the external causes, the comprehensive fire extinguishing measures were carried out to seal the fire zone.Based on the gas varying laws, the burning state in the fire zone was analyzed, and the fire behavior was determined by enhancing the oxygen concentration in the fire zone. According to ＂Safety Regulations in Coal Mine＂, N1203 working face was safely unsealed, indicating a success- ful unsealing of fire zone for high gas coal mine.
